CHAP. XI. Whether it be lawfull to sleepe having taken a purge.

WHether we may sleep having taken a purge Physiti∣ans disagree, but there is need of a distinction; for if the purging medicine be gentle and benigne, having taken it we ought not to sleep, least the medicine should be carried away and overcome by nature, and its action hindred, but if the purging medicine be stronger, and requires greater heate that it may be brought into action, sleepe may be granted to the sick, yet moderate, which may only further the activity of the medicine, but not impead evacuation, but afterwards to abstaire from sleep untill perfect and sufficient purgation

be made; moreover for the same reason, after taking strong purges tis lawfull to sleepe a little while, that the malignity of the medicine may be resisted by the more plentifull heat, occasioned by sleepe, and those troubles which the medicine occasioneth may lesse be discerned in sleepe, and so the me∣dicine retayned without trouble or molestation, may right∣ly be reduced into action.
